EDWIN S. DECKER, OF MALDEN, MASSACHUSETTS, ASSIGNOR TO GIBBY FOUNDRYCOMPANY, OF EAST BOSTON, MASSACHUSETTS, A CORPORATION OF MASSACHU-SETTS.

SASH-WEIGHT.

T 0 all-whom it may concern:

Be it known that I, EDWIN- S. DECKER, a

rsubject or the lung of Great. Britain, and

resident of Malden, county of Middlesex sections can be detachablyconnected to make up the weight requisite to counter-balance a givenwindow-sash.

One of the objects of my presentinvention is the production of asash-weight which can be constructed easily at practically a nominalcost yet which is so arranged that as much metal as possible is presentin each unit or section.

Another object of my invention is the production of a sash-weightwhereof the separate members, units or sections thereof can be connectedand disconnected rapidly and easily, bearing in mind the narrow orcontracted spaces in which the sash-weights must operate, and the unitsor sections are so constructed that when locked together they can behandled with safety and in a convenient manner.

Inasmuch as the members or sections must frequently be coupled togetherwhen two adjacent sections are substantially at right angles to eachother I have constructed my novel sash-weight accordingly, so that whenadjacent sections are substantially alined they cannot by anypossibility become uncoupled or disconnected.

The novel features of my invention will be fully described in thesubjoined specification and particularly pointed out in the followingclaim.

Figure 1 is a front elevation and part section of a sash-weightembodying my invention, two members, units or sections be ing coupledtogether; Fig. 2 is a side elevation of the device shown in Fig. 1; Fig.3 is a perspective view of one of the weight members or sections; Fig. 4is a top plan view of one of the members; Fig. 5 is a bottom plan viewthereof, Figs. 4 and 5 being taken in the position of the weight shownin Fig. 2.

Specification of Letters Patent.

Application filed October 16, 1909.

Patented Jan. 11, 1910.

Serial No. 522,917.

The sash-weight member, unit or section (the terms being usedsynonymously) is made as a casting comprising a body 1 of suitablelength and preferably rectangular in cross-section, its lower end beingof reduced width to form two substantially central and longitudinallyextended lugs 2, 2, having opposite inturned ends 3, forming hookshaving an entrance slot 4; communicating with the open space or recess 5between the lugs 2.

In practice the lower ends of the hooks so formed are preferablyslightly rounded or convexed, as best shown in Fig. 1.

At its opposite end the body has longitudinally extended ears 6, 6, theouter faces of which are slightly convergent and form continuations ofthe opposite sides or faces of the body, the opposite sides of said earsbeing tapered from the body to their outer ends, as clearly shown inFigs. 1 and 3. These ears are at right angles to the entrance slot l,but their parallel inner faces are parallel to the opposite side edgesof the lugs 2, and said ears are laterally separated to form asubstantially rectangular opening 7 for the reception of the hooks of aconnected member, as shown. A cross-bar 8 joins the outer or smallerends of the ears and as shown said bar is of greater width thanthickness, the width being almost as great as the distance between theinner faces of the lugs 2 while the thickness of the bar is sjightlyless than the width of the entrance s 0t 4.

When two members are coupled together the inturned ends 3 of the lugs 2of one member extend beneath the cross-bar 8 of the next member into theopening 7, while the said cross-bar lies within the open space or recess5 of the first-named member, this being very clearly illustrated in Fig.1.

So long as coupled members are in substantial alinement it is impossiblefor them to become uncoupled, for they are practically locked togetherwhile articulated so that the members can have a slight relativeswinging movement within the weight-box of the window casing.

To couple or uncouple the weight members it is necessary to bring thetwo adjacent members into position substantially at right angles to eachother, as illustrated by dotted lines, Fig. 1. This movement brings thecross-bar of one member, with its thickness opposite the slot 4 betweenthe hooks of the other member, so that by moving the two members towardor from each other, maintaining the right-angle position, the crossbarwill slip through slot 4 into the opening 5, when assembling, or thecross-bar will slip out of the slot when uncoupling.

hen assembling two members, after the cross-bar of one passes throughthe slot into the opening 5 of the other member the members are broughtinto alinement and they are then completely coupled together.

As many of the members are coupled to gether as may be necessary toprovide the proper counter-balance for the window-sash, the uppermostmember of the series being attached to the saslrcord A, Fig. 1, bylooping the latter around the cross-bar 8.

For convenience in centering the cord. or other suspending member I mayprovide slight depressions 9 on opposite sides of the cross-bar, midwaybetween its ends, to receive and position the engaging part of thesuspending member A.

It is customary in assembling the weight members to attach one to thesash-cord, couple another member to the lower end of the first member,and proceed in like manner until the required number have been coupledtogether, the additions being made through the opening at the lower endof the weight-box usually provided.

The castings can be made very cheaply, they require practically nopolishing, and successive members hang plumb and true from the adjacentones above.

Having fully described my invention, What I claim as new and desire tosecure by Letters Patent is A sashweight member comprising a. bodyprovided at one end With substantially central and longitudinallyextended lugs, having opposite inturned ends, to form hooks having anentrance slot therebetween, the opposite end of the body havinglongitudinally extended ears at right angles to such slot and laterallyseparated to form an open ing for the reception of the hooks of aconnected member, and a cross-bar joining the ears and adapted to passthrough the entrance slot or an adjacent member when the two members aresubstantially at right angles to each other.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
